Sapin, Academician of the Russian Academy of Medical Sciences, headed the Laboratory of Functional Anatomy at the Research Institute of Human Morphology of the Russian Academy of Medical Sciences for more than 40 years (currently the Research Institute of Human Morphology, a branch of the Petrovsky National Research Center of Surgery). Mikhail R. Sapin was not only the laboratory’s head of research, but he was also actively involved in the Institute’s life. As a member of the Academic Council, he helped define research directions and steer the Institute through difficult times. For many decades, Sapin served as a member of the Scientific and Methodological Council under the USSR Ministry of Health (later the Ministry of Health of the Russian Federation), and as Chair of the Functional Anatomy Task Group of the Morphology Research Council at the Presidium of the USSR Academy of Medical Sciences (later the Russian Academy of Medical Sciences). Sapin was well respected among morphologists; specialists from across the Soviet Union, and later from Russia and neighboring countries, sought his advice and guidance. For the morphological community, he was a true leader. Since 1974, he had served as Deputy Chair of the All-Union Scientific Society of Anatomists, Histologists, and Embryologists, becoming its Chair in 1988. In 1992, Sapin founded the International Association of Morphologists of the CIS Countries and served as its President; from 2006 to 2015, he was Honorary President of the Association.</p></abstract><trans-abstract xml:lang="ru"><p>Академик Российской академии медицинских наук Михаил Романович Сапин более 40 лет руководил лабораторией функциональной анатомии Научно-исследовательского института морфологии человека РАМН (в настоящее время — Научно-исследовательский институт морфологии человека имени академика А.П. Авцына ФГБНУ «Российский научный центр хирургии имени академика Б.В. Петровского»). Михаил Романович Сапин был не только научным руководителем лаборатории, но и принимал активное участие в жизни Института морфологии человека. Он был членом Учёного совета и участвовал не только в формировании направлений научных исследований, но и в определении судьбы Института в сложные периоды его существования. В течение многих десятков лет М.Р. Сапин был членом научно-методического совета при Министерстве здравоохранения СССР (позднее Министерство здравоохранения РФ), Председателем Проблемной комиссии «Функциональная анатомия» Научного совета по морфологии при Президиуме Академии медицинских наук СССР (позднее Российская академия медицинских наук). М.Р. Сапин пользовался большим авторитетом среди учёных, к нему на консультацию и за помощью приезжали морфологи из разных уголков Советского Союза, а в дальнейшем — России и стран ближнего зарубежья. Для морфологического сообщества Михаил Романович был настоящим лидером. С 1974 года он выполнял обязанности заместителя председателя Всесоюзного научного общества анатомов, гистологов, эмбриологов, а в 1988 году стал председателя этого общества. В 1992 году Михаил Романович организовал Международную ассоциацию морфологов стран СНГ и стал её Президентом, а с 2006 по 2015 год был почётным Президентом этой ассоциации.</p></trans-abstract><trans-abstract xml:lang="zh"><p>俄罗斯医学科学院院士Mikhail Romanovich Sapin四十余年来一直担任Research Institute of Human Morphology功能解剖学实验室主任（现为Petrovsky National Research Center of Surgery——Research Institute of Human Morphology named after Academician A.P. Avtsyn）。Sapin院士不仅是Institute of Human Morphology功能解剖学实验室的主任，还积极参与该研究所的学术与组织工作。他是研究所学术委员会成员，长期参与科研方向的制定及研究所发展的重大决策，尤其在研究所处于困难时期发挥了重要作用。数十年来，Sapin院士一直担任苏联卫生部（后为俄罗斯联邦卫生部）科学方法委员会委员，并主持苏联医学科学院（后为俄罗斯医学科学院）形态学学术委员会下设的“功能解剖学”专题委员会。Sapin院士在科学界享有崇高声望，来自苏联各地以及后来的俄罗斯和独联体国家的形态学家们纷纷前来向他请教与合作。Sapin被公认为形态学界的杰出学术领袖。自1974年起，Sapin院士任全苏解剖学、组织学与胚胎学学会副主席；1988年起担任该学会主席。1992年，Sapin倡议成立独立国家联合体International Association of Morphologists并出任首任主席；2006年至2015年间，担任该协会名誉主席。</p></trans-abstract><kwd-group xml:lang="en"><kwd>academician M.R.
